• Own the roadmap and delivery of enterprise data platforms and analytics products, including data lakes/warehouses, ETL/ELT, streaming and data APIs.
• Provide hands‑on technical leadership: design and review architecture, implement or optimise key components, and resolve production incidents as required.
• Drive adoption of Databricks best practice (Spark optimisation, Delta Lake, Unity Catalog) and core cloud platform patterns.
• Productionise AI/ML: guide feature engineering, model deployment, monitoring, versioning, explainability and MLOps workflows.
• Establish and enforce CI/CD, automated testing, observability and incident response for data pipelines, models and analytics services.
• Define and enforce data governance, security, privacy and compliance standards in partnership with legal and security teams.
• Partner with business leaders, product managers and consulting teams to translate business problems into scalable data and AI solutions; manage stakeholder expectations and prioritisation.

• Hands‑on Databricks experience (Spark optimisation, Delta Lake, workspace/job orchestration, Unity Catalog) at scale.
• Strong practical experience building and operating data solutions on AWS (e.g., S3, Glue, Redshift/Athena, Lambda, EKS/ECS; infrastructure as code such as CloudFormation or Terraform).
• Solid understanding of AI/ML production patterns, including model development, deployment, monitoring, drift detection and MLOps.
• Strong software and data engineering skills: Python and SQL required; Scala/Java advantageous. Experience with Spark, data modelling, ETL/ELT and streaming fundamentals.
